Impact of non-surgical periodontal therapy on OHRQoL in an obese population, a randomised control trial.

BACKGROUND: Oral Health Related Quality of Life (OHRQoL) is an important measure of disease and intervention outcomes. Chronic periodontitis (CP) is an inflammatory condition that is associated with obesity and adversely affects OHRQoL. Obese patients with CP incur a double burden of disease. In this article we aimed to explore the effect of Non-Surgical Periodontal Therapy (NSPT) on OHRQoL among obese participants with chronic periodontitis. MATERIALS AND METHODS: This was a randomised control clinical trial at the Faculty of Dentistry, University of Malaya. A total of 66 obese patients with chronic periodontitis were randomly allocated into the treatment group (n=33) who received NSPT, while the control group (n=33) received no treatment. Four participants (2 from each group) were non-contactable 12 weeks post intervention. Therefore, their data were removed from the final analysis. The protocol involved questionnaires (characteristics and OHRQoL (Oral Health Impact Profile-14; OHIP-14)) and a clinical examination. RESULTS: The OHIP prevalence of impact (PI), overall mean OHIP severity score (SS) and mean OHIP Extent of Impact (EI) at baseline and at the 12-week follow up were almost similar between the two groups and statistically not significant at (p=0.618), (p=0.573), and (p=0.915), respectively. However, in a within-group comparison, OHIP PI, OHIP SS, and OHIP EI showed a significant improvement for both treatment and control groups and the p values were ((0.002), (0.008) for PI), ((0.006) and (0.004) for SS) and ((0.006) and (0.002) for EI) in-treatment and control groups, respectively. CONCLUSION: NSPT did not significantly affect the OHRQoL among those obese with CP. Regardless, NSPT, functional limitation and psychological discomfort domains had significantly improved.

Tooth mortality in smokers and nonsmokers in a selected population in Sana'a, Yemen.

BACKGROUND AND OBJECTIVE: Tobacco smoking has been shown to be a major risk factor for tooth loss. The present study was designed to examine tooth mortality and the patterns of tooth loss in smokers and nonsmokers over a wide age range in a selected population from Sana'a, Yemen. MATERIAL AND METHODS: A total of 2506 persons between the ages of 15 and 64 years were examined, and every permanent tooth was assessed. Missing teeth included both extracted and missing teeth. Individuals currently smoking one or more boxes of cigarettes (20 cigarettes) a day for 5 years were considered as smokers, whereas individuals with no smoking history were considered as nonsmokers. RESULTS: Smokers had a higher mean tooth loss than nonsmokers. The difference was statistically significant at p < 0.001. Mean tooth loss was significantly higher in smokers across all age groups, except for those in the 45-54 years age group. Smokers had a significantly higher mean upper tooth loss than nonsmokers. Tooth loss decreased from the incisors to the canines and then increased, with peak loss in the first molars. CONCLUSION: Tooth loss among smokers is significantly higher than among nonsmokers. The central incisors, lateral incisors and first molars were the most commonly missing teeth in smokers, compared with nonsmokers.
